BOAO, Hainan province: Liquid milk producer China Mengniu Dairy will invest more this year to expand raw milk bases in the country, according to a senior executive.

"Mengniu plans to pour more money to acquire shares in existing pastures or build up its own pastures," Executive Director and Vice-President Yang Wenjun told reporters on Friday at the sidelines of the eighth Boao Forum for Asia Annual Conference in Hainan province.

The company aims to increase the number of its mega-size pastures, each of which can house up to 10,000 cows, to 20 over the next three years. It currently has seven such pastures in Inner Mongolia, Shandong, Heilongjiang and Anhui.
